How AfriCommex® Silo Certificate® Works
An AfriCommex Silo Certificate® is a warrant issued by our silo/warehouse person to a farmer depositing
goods in the warehouse. A certified warehouse manager then issues in triplicate, an authorized negotiable or
a non negotiable AfriCommex Silo Certificate®. This certificate is an irrevocable document that evidences a
contract for storage of goods. AfriCommex Silo Certificate® is accepted by the commercial banks as collateral
security for grant of loan against the goods stored in our warehouses/silos.

By multiplying the specific volume (in m³/t) by the quantity of grain (in t) to be stored, one obtains the volume (in m³) occupied by the bags in
the storehouse.
Height of the stacks
The maximum height of the stacks depends on the type of bags used to store grain.
For bags made of plant fibre (jute, sisal, etc.) maximum heights can be 5-6 metres, while for plastic bags (woven polythene) they should not
exceed 3 metres.
Furthermore, enough space must be left between the roof of the building and the tops of the stacks for a workman to move about freely.
Passages and corridors
The width of the passages between the batches can vary from 2 to 4 metres, while the corridors between the walls and the batches must have
a minimum width of 1 metre.

AfriCommex Silo Specifications
Dimensions of the buildings
Storehouses are generally rectangular, about twice as long as they are wide. Appropriate dimensions of these buildings can be determined
with knowledge of:
•        the type, quantities and specific volume of grain to be stored in bags;
•        the maximum height of the stacks of bags;
•        the number of batches to be separated and the width of the access corridors;
•        the extent and arrangement of service areas.
Specific volume
The specific volume means, for each type of grain, the space occupied by a tonne of product stored in bags. Its unit of measurement is the
cubic metre per tonne of product (m³/t).
